My 2009 Camry's cruise control forces the car to speed up above the set mph when going UPHILL. It usually goes up 7-10 mph over the speed I set. After many trips to the dealership they are claiming that this is normal. However the National Traffic and Safety Board (or whatever its technical name is) states that any vehicle's cruise control cannot exceed the set speed by more than 3 mph.My 2009 Camry's cruise control forces the car to speed up above the set mph when going UPHILL.

All Toyota auto trans cars downshift when descending a hill when you tap the brake. This is called "Downhill Shift Logic"; what this is for is to eliminate the double shift when you come to the bottom of a hill and then accelerate. Normal condition. Usually happens above 38 MPH.
Also: The cruise will accelerate when going uphill. Normal condition.Plus: The cruise will not disengage back to the set MPH after you top the hill. Toyota recommends to disengage the cruise when encountering steep terrain.

Take your vehicle to a Toyota Dealership. Advise them that you want your vehicle checked for an applicable bulletin. The bulletin number is T-SB-0033-08. They will, if you vehicle is in the build sequence applicable to this specific bulletin, replace the Line Pressure Control Solenoid Assembly. This is a 5 year/60,000 mile warranty part. No charge to you.

Figure 2-3 hours for them to change it.

When a new customer takes delivery of there new car I always take them out for a demonstration of how "the new computer controlled fuzzy logic engine gearbox system" works.ergo without using the gas pedal put the car in drive and let it accelerate, all the way, on its own.then using 1/2 gas, same again and lastly full gas."now, when you drive it ,be as gentle as you can, to save gas and wear on the car ,you will notice the gears will change ,much lower down the rev range than a heavy footed driver will get.and vice versa.you will be amazed at how many customers
tell me that there mileage has got much better...
and yes your dealer is right if ther was a problem then d3 would come up.hope this gives you info needed.

Sounds like the torque converter isn't unlocking quick enough. Drive at 45mph,keep foot on gas and use other foot to touch the brake and watch the tach to see if it speeds up,when converter releases. Check trans fluid level hot.If it is more than a couple years old,change. Use the correct fluid for Toyota and add a bottle of Lubgard. Have the throttle positon senor scanned and check any idle control circuits. Throttle Body may need cleaning.
